Governments throughout the world act on the assumption that the welfare of their people depends largely on the economic strength and wealth of the community. 1) Under modern conditions, this requires varying measures of centralized control and hence the help of specialized scientists such as economists and operational research experts. 2) Furthermore, it is obvious that the, strength of a country’s economy is directly bound up with the efficiency of its agriculture and industry, and that this in turn rests upon the efforts of scientists and technologists of all kinds. It also means that governments are increasingly compelled to interfere in these sectors in order to step up production and ensure that it is utilized to the best advantage. For example, they may encourage research in various ways, including the setting up of their own research centers; they may alter the structure of education, or interfere in order to reduce the wastage of natural resources or tap resources hitherto unexploited; or they may co-operate directly in the growing number of international projects related to science, economics and industry. In any case, all such interventions are heavily dependent on scientific advice and also scientific and technological manpower of all kind. 3) Owing to the remarkable development in mass-communications, people everywhere are feeling new wants and are being exposed to new customs and ideas, while governments are often forced to introduce still further innovations for the reasons given above. At the same time. The normal rate of social change throughout the world is taking place at a vastly accelerated speed compared with the past. For example, 4) in the early industrialized countries of Europe the process of industrialization-with all the far-reaching changes in social patterns that followed-was spread over nearly a century, whereas nowadays a developing nation may undergo the same process in a decade or so. All this has the effect of building up unusual pressures and tensions within the community and consequently presents serious problems for the governments concerned. 5) Additional social stresses may also occur because of the population explosion or problems arising from mass migration movements-themselves made relatively easy nowadays by modern means of transport. As a result of all these factors, governments are becoming increasingly dependent on biologists and social scientists for planning the appropriate programs and putting them into effect.1.

Each summer, no matter how pressing my work schedule, I take off one day exclusively for my son. We call it dad-son-day. This year our third stop was the amusement park, where he discovered that he was tall enough to ride one of the fastest roller coasters(过山车)in the world. We blasted through face-stretching turns and loops for ninety seconds. Then, as we stepped off the ride, he shrugged and, in a distressingly calm voice, remarked that it was not as exciting as other rides he’d been on. As I listened, I began to sense something seriously out of balance.Throughout the season, I noticed similar events all around me. Parents seemed hard pressed to find new thrills for indifferent kids. Surrounded by ever-greater stimulation, their young faces were looking disappointed and bored.Facing their children’s complaints of “nothing to do”, parents were shelling out large numbers of dollars for various forms of entertainment. In many cases the money seemed to do little more than buy transient relief from the terrible moans of their bored children. This set me pondering the obvious question: “How can it be so hard for kids to find something to do when there’s never been such a range of stimulating entertainment available to them?”What really worries me is the intensity of the stimulation. I watch my little daughter’s face as she absorbs the powerful onslaught(冲山)of arousing visuals and bloody special, effects in movies.Why do children immersed in this much excitement seem starved for more? That was, I realized, the point. I discovered during my own reckless adolescence that what creates excitement is not going fast, but going faster. Thrills have less to do with speed than changes in speed.I’m concerned about the cumulative effect of years at these levels of feverish activity. It is no mystery to me why many teenagers appear apathetic(麻木的)and burned out, with a “been there, done that” air of indifference toward much of life. As increasing numbers of friends’ children are prescribed medications-stimulants to deal with inattentiveness at school or anti-depressants to help with the loss of interest and joy in their lives-I question the role of kids’ boredom in some of the diagnoses.My own work is focused on the chemical imbalances and biological factors related to behavioral and emotional disorders. These are complex problems. Yet I’ve been reflecting more and more on how the pace of life and the intensity of stimulation may be contributing to the rising rates of psychiatric problems among children and adolescents in our society.1. The author felt surprised in the amusement park at the fact that _____.2. According to the author, children are bored _____.3. From his own experience, the author came to the conclusion that children seem to expect _____.4. In Para.6, the author expresses his doubt about the effectiveness of trying to change children’s indifference toward much of life by _____.5. In order to alleviate children’s boredom, the author would probably suggest _____.

Despite the modern desire to be easy and casual, Americans from time to time give thought to the language they use, to grammar, vocabulary, and official languages. And, as on other issues, they divide into two parties. The larger, which includes everybody from the plain people to the professional writer, takes it for granted that there is a right way to use words and construct sentences and many wrong ways. The right way is believed to be clearer, simpler, more logical, and hence more likely to prevent error and confusion. Good writing is easier to read; it offers a pleasant combination of sound and sense.Against this majority view is the doctrine of an opposing minority, who make up for their small number by their great learning and their place of authority in the school system and the world of scholarship. They are the professional linguists, who deny that there is such a thing as correctness. The language, they say, is what anybody and everybody speaks. Hence there must be no interference with what they regard as a product of nature. They denounce all attempts at guiding choice; their governing principle is summed up in the title of a speech by a distinguished member of the profession: “Can Native Speakers of a Language Make Mistakes?”Within the profession of linguists there are, of course, fighting factions, but, on this conception of language as a natural growth with which it is criminal to interfere, they are at one. In their arguments one finds appeals to feelings of social equality (all words and forms are equally good) and individual freedom (one may do what one likes with one’s own speech). These beliefs further suggest that the desire for correctness, the very idea of better or worse in speech, is what is left over from noble and humble times. To the linguists, change is the only rule to be obeyed. They consider it to be equal with life and accuse their critics of being clock-reverses, enemies of freedom, menaces to “life”.1. The larger of the two groups mentioned believes that _____.2. According to the passage, the professional writer _____.3. The professional linguists _____.4. The desire for correctness is considered by some people to be _____.5. The only rule to be obeyed is _____.
